IMPROVEMENT IN MOLDS FOR MENDING CRACKED BELLS.

Specification forming part of Letters Patent No. 152,170, dated June 16, 1874; application filed June 17, 1873.

Z'o all whom it may concer-n:

Be it known that I, DANIEL L. RIGGS, of Salem, county of Marion, in the State of Oregon, have invented a Process for Mending Cracked or Broken Bells, of which the following is a specification.:-

My invention has for its object to mend fractures in bells, and at the same time maintain a homogeneous mass throughout, and preserve the tone of the bell. My invention consists of a certain combination and arrangements of two furnaces with a mold in relation tothe bell.

I am aware that metals have heretofore been soldered together per se, or burned together as it is termed; butall attempts that I am aware of being made heretofore of applying this process to the mending of bells have signally failed to make the mass homogeneous, and preserve the tone of the bell.

In the accompanying drawings, Figure l is a perspective view of a bell having my improved apparatus applied toit. Fig. 2 is a vertical cross-section of the same.

each side of the bell to d d, and has the cham ber B, the center of which is contiguous to the crack a. Inside of the bell I make a combined furnace and mold, O and E, which has a diaphragm, z', passing across the bell, and making the furnace-chamber B. Oommeneing at the top of the crack a, and extending to its bottom, is made a mold, E, in the curved. side of the furnace C', the opposite side of the mold bein g formed by the convex side of furnace C, which bears against the outside of the bell.

The operation is as follows: The furnace chambers C C' being supplied with fuel and ignited, a blast is thrown on them until the edges of the crack are fused and united, thc deiicient met-al being supplied by other metal already melted and prepared, poured into the mold E.

Having thus described my invention, what I claim as new is- An apparatus for mending broken bells, consisting of the external furnace-chamber O, in combination with the internally-arranged furnace C', and the intermediate mold E around the crack or fracture a, all constructed and arranged substantially as and for the purpose set forth.
